What''s the best way to get the URL for a resource when my ruby code has the full pathname.

you could use File.basename to return just the filename then prepend with ''/images/'' On 8/25/06, Jeremy Wells <jwells-cH1Rxhrj+4a/3pe1ocb+s/XRex20P6io@public.gmane.org> wrote:> > What''s the best way to get the URL for a resource when my ruby code has the > full pathname.
